First things first, sweetie! Preheat the oven to 350°F (175°C). Go ahead and line our [12-cup Muffin Tin] with those paper liners you like, it makes cleanup so much easier for mom later!
In the big bowl, I want you to whisk together the [whole wheat flour], [vanilla protein powder], [baking powder], [baking soda], and [salt]. Whisk it gently so the flour doesn't fly out of the bowl like a snowstorm!
In the separate medium bowl, whisk the [plain Greek yogurt], [eggs], [maple syrup], [melted coconut oil], [vanilla extract], and that yummy [lemon zest] if we're using it. This yogurt mixture is the secret weapon that keeps them super moist
Pour the wet yogurt mixture into the dry flour mixture. Now, switch to the spatula and stir just until you can't see the flour anymore. Remember what I taught you? Don't overmix, or our muffins will turn into hockey pucks!
Here is the most important part. Gently fold in the [blueberries]. Be super soft with them, Livie! If we smash them, the whole batter turns grey and purple. Just a few turns of the spatula is enough
Divide the batter evenly into the muffin cups (they should be about ¾ full). Pop them in the oven and bake for 18 to 22 minutes. We'll know they are done when the tops are golden and a toothpick comes out clean
I know it smells amazing and you want one right now, but let them cool in the pan for 5 minutes, then move them to a wire rack. If we eat them too hot, they crumble apart!
